The State of World Population 2019 Report, UNFPA’s flagship publication, traces the achievements, drawbacks and challenges in ensuring rights and choices for all in both the global and regional backdrop in the context of two important milestones in the field of reproductive health and rights: 50 years since UNFPA was founded, and 25 years since our landmark International Conference on Population and Development (ICPD) in Cairo. The report has been published since 1978 and is used to give wider visibility to critical and emerging issues and trends in world population and demographics.
